Abstract
The utility model provides a crown spring jack which is used for insertion of an inserting needle. The crown spring jack comprises the following components: a packaging circular reed which is jointed with the inserting needle through insertion, an inner sleeve and an outer sleeve which are successively sleeved outside the packaging circular reed. The packaging circular reed is provided with two closed edges which are respectively connected with a plurality of contact strips. The contact strips are clamped between outside of the inner sleeve and inside of the outer sleeve. The inner sleeve is provided with a plurality of grooves. The contact strips are inserted into the grooves. The width of each groove is adapted with the thickness of each contact strip, thereby fixing the packaging circular reed to the inner sleeve. The crown spring jack provided by the utility model can ensure no rebound failure of the packaging circular reed totally, thereby ensuring high reliability. Simultaneously, the packaging circular reed is inserted into the groove after torsion, and the torsion angle is precisely calculated beforehand. Because of the foolproof performance, consistent torsion angle of the products in a same standard can be ensured, thereby ensuring stable inserting and pulling forces.
